LAVATORY.

Specification of Letters Patent.

Patented July 20, 1909.

Application filed December '7, 1907. Serial No. 405,616.

To all whom it may concern:

Be it known that I, HENRY PODMORE, of Trenton, Mercer county, NewJersey, have invented a new and useful Improvement in Lavatories, ofwhich the following is a full, clear, and exact description, referencebeing had to the accom anying drawings, forming part of thisspecification, in which the figure isna vertical cross-section of myimproved construction.

My invention relates to lavatories of earthy material having backscemented and fired thereto.

It is customary in the art to set the separately molded back on the rearortion of the lavatory slab with a horizontaFjoint and to cement themtogether, and then fire them in a kiln. The back piece usually warpsduring the firing and is therefore ground on its rear face to smooth thewarp or twist and to make it fit against any desired surface. Thisgrinding operation extends over and is apt to develop a crack at thejoint where the back is cemented to the lavatory, rendering the lavatoryunsalable. Rejections from this cause usually run as high as 20% of thetotal production. With my construction this percentage of loss is whollyavoided as the joint is not attacked by the grinding o'eration, sincethe slab or top plate of the avatory abuts against the back pieceinstead of the back piece being placed upon the rear portion of the slabor top plate of the lavatory as in the general practice.

Referring to the drawings, 2 is the lavatory slab or top plate, having abasin 3. The back piece 4 is set against the rear end of the slab 2forming a vertical joint 5. In making the device, the lavatory andbackpiece are molded separately and while green ('5. e. before firing) arecemented together at the joint 5. The lavatory with back iece attachedis then placed in a kiln and fired.

After the firing the usual grinding operation takes place to make therear vertical surface 6 of the back piece a true surface. It will bereadily seen that this grinding operation cannot attack or affect thevertical joint 5.

From the foregoingit will be seen that my invention is not confined tothe precise construction shown in the drawings, since What I claim is 1.A lavatory of earthy material having a slab abutting against a backpiece with avertical extending joint.

2. A lavatory of earthy material having a back piece at an angle to theslab thereof and against the front face of which said slab abuts.

3. A lavatory of earthy material having a slab abutting against a backiece with a vertically extending joint and fired thereto.

4. A lavatory of earthy material having a back piece at an angle to theslab thereof, and against the front face of which said slab abuts, saidback piece and said slab being inte ral. 7

5. The process of manufacturin lavatories which consists in separatelymjding the back piece and the slab of a lavatory, oementing themtogether with a vertical joint and then firing and finishing the twopieces thus joined.

6. The process of manufacturing lavatories which consists in separatelymolding a back piece and a slab, abutting the slab againstthe back pieceand cementing the two pieces together to form a vertically extendingjoint and firing and finishing the pieces thus joined.

In testimony whereof, I have hereunto set my hand.
